To obtain further independent predictions, in particular for the modelling of
non-perturbative effects, we compile additional results from
HERWIG  [1]}, [2]}, version 7.2.1, and PYTHIA  [3]},
version 8.303. For both generators we consider the
\(\mu ^+\mu ^-j\) -production process at leading order,In the
case of HERWIG, we could have also included NLO-accurate matrix
elements [4]}, [5]}. However, since the baseline for our MC simulations are SHERPA MEPS@NLO predictions, we restrict ourselves to leading-order matrix elements for
simplicity.
